Spicy Sweet Potato Fries
Equipment
- 1 Large Baking Sheet (lined with parchment paper)
- (1) Chef’s knife
- 1 cutting board
- 1 Mixing Bowl (optional, for tossing)
- 1 Spatula or Tongs (for flipping)
Ingredients
- 2 large sweet potatoes about 2 lbs / 900 g
- 2 Tbsp cooking oil any neutral oil, like olive or canola
- 1 tsp Creole seasoning or spicy seasoning salt
Instructions
- Preheat the oven: Set your oven to 400°F (200°C) and line a large baking sheet with parchment paper. This step ensures easy cleanup and helps prevent the fries from sticking.
- Prepare the sweet potatoes: Peel the sweet potatoes and slice them into uniform sticks about ¼–½ inch thick. Keeping the size consistent helps them cook evenly and achieve the best crispness.
- Coat with oil: Place the sweet potato fries on the lined baking sheet and drizzle with the cooking oil. Toss them thoroughly with your hands or a spatula until each piece is lightly coated, which ensures even browning. Spread the fries out again into a single layer—overcrowding will make them steam instead of crisp.
- Bake until golden and blistered: Transfer the tray to the preheated oven and bake for 40–45 minutes. Stir or flip the fries every 20 minutes to help them crisp on all sides. They are ready when the edges are deeply golden and slightly blistered.
- Season and serve: As soon as the fries come out of the oven, sprinkle them generously with Creole seasoning or your preferred spicy seasoning salt. Toss gently to distribute the flavor, then serve immediately while hot and crispy.
Notes
- Uniformly cut fries bake more evenly and crisp better.
- Parchment paper helps prevent sticking and makes cleanup simple.
- Flipping halfway ensures golden edges on all sides.
- Season immediately after baking so the spices cling to the hot fries.
- These fries taste best straight from the oven but can be reheated for later.
Chef’s Secrets for Perfect Fries
The key to great sweet potato fries lies in preparation and spacing.
Cutting the potatoes into consistent sticks prevents uneven cooking, while arranging them in a single layer allows hot air to circulate and create that sought-after crisp texture.
A light but thorough oil coating is equally important—it helps caramelize the natural sugars in sweet potatoes, resulting in golden edges and rich flavor.
Finally, always season after baking, as spices can burn if applied too early.
Serving Suggestions Worth Trying
These fries are versatile enough to complement countless meals.
Pair them with burgers, grilled chicken, or roasted vegetables for a wholesome dinner, or enjoy them as a snack with creamy dips like garlic aioli, chipotle mayo, or even classic ketchup.
For a lighter option, serve alongside a fresh green salad or a hearty grain bowl. They’re also a fun side for brunch when paired with eggs and avocado toast.
Storage Tips for Best Results
Sweet potato fries are at their crispiest when freshly baked, but you can store leftovers in an airtight container in the refrigerator for up to three days.
To reheat, skip the microwave, as it makes them soggy—instead, spread the fries on a baking sheet and warm them in a 375°F (190°C) oven for about 10 minutes.
If you’d like to prepare ahead, cut the raw potatoes and store them in cold water in the fridge for up to 24 hours before baking.
Frequently Asked Questions
Can I make these fries in an air fryer?
Yes! Air frying works beautifully. Cook at 375°F (190°C) for 15–18 minutes, shaking the basket halfway, until crisp and golden.
Do I have to peel the sweet potatoes?
Not at all. The skin is edible and adds extra fiber and nutrients. Just scrub the potatoes well before slicing if you prefer to keep it on.
Why aren’t my fries crispy?
Overcrowding is usually the culprit. Spread fries in a single layer with space between each piece so hot air can circulate.
Also, avoid excess oil, which can make them soggy.
Can I use other seasonings instead of Creole?
Absolutely! Try smoked paprika, garlic powder, chili flakes, or even a sprinkle of cinnamon and cayenne for a sweet-spicy twist.
Are these fries healthy?
Yes, they are a nutritious alternative to deep-fried fries.
Sweet potatoes are rich in fiber, antioxidants, and complex carbs, while baking keeps the fat content lower compared to frying.
